South Florida Guys: St Augustine growth rates?

What do you guys estimate a growth rate for healthy, well fertilized, irrigated St Augustine in South Florida?

(IE: __ inches per week in the summer _____ inches per week in the winter?)

Im curious because, I have a customer who uses a National Fert Co, and they lay it on heavy, and OFTEN. Even during the winter months I am chopping off 3-5 inches after 10-14 days. The summer forget about it...Its like the amazon.

I measured today and in one spot, I took off 9 inches after 13 days, and it hasnt even started to rain yet.

Is this amount of growth excessive? And can you actually over fertilize St Aug?

Hello from Lehigh Acres,

I don't know the exact growth rates, but I'd definately call
what you described excessive growth.

It's sometimes compounded by the customer over-irrigating.

Yes, I think that over-fertilizing/over-irrigating
can lead to a "spongey" weak rooted lawn.
Basically killing it with kindness.

Having said that, we've been seeing unusually high
growth rates on many of our irrigated/fertilized St.
Augustine lawns for this early in the season.
We've been mowing many of them weekly already
just to keep them from getting out of hand.
Although now it seems that they may be slowing down enough that we should be able to extend
them back out to 10-14 days for a while. It was unexpected growth, because like you mentioned we haven't had much rain at all.

We're mulching at a 4" cutting height.

Bob,

No doubt there is some sponge'yness going on particularly near the culvert areas. I would agree with the little bits of rain we have had so far things are growing faster then a normal year.

Normally I dont go to weekly schedule until May 1st, And even then sometimes end up skipping, or doing drive by's on a lot of accounts until the rain starts.

I cut at 5 inches. I also forgot to mention the customer lost two royal's this past year. I know excessive fert can lead to problems in palms.

When i said I took off 9 inches, that doesnt include my 5 inch cut height. So this lawn had grown to 14 inches high in 13 days.

No I never scalp anything. I set my mower at 5 inches for St Aug. The lawn grew from my regular cutting height of 5 inches to as high as 14 inches.

So it grew, or I chopped off as much as 9 inches, in 13 days.
